Get a sun-kissed look without the damaging effects of UV exposure with Neutrogena Build-A-Glow Gradual Self Tanning Mousse. This sunless tanning face and body mousse from a dermatologist-recommended brand makes it easy to get glowing skin. The bronzing mousse provides buildable, natural-looking color that's visible after 2-4 hours and lasts for several days. This self-tanning lotion is formulated with skin-conditioning emollients and argan oil, an ingredient rich in natural oils. The customizable tanning mousse is developed for a natural looking color that starts to develop gradually over time. The foam self tanner has a lightweight formula that's sulfate-, paraben-, and dye-free, and can be used daily and reapplied for deeper color. To use, apply 1-2 pumps into hands and then smooth evenly over freshly cleansed, exfoliated, and dry skin. Apply sparingly to elbows, knuckles, knees, and ankles. Blend thoroughly and wait at least 8 hours before reapplying for deeper color.
